● FILLET RADIUS
This function is used to identify fillets which radius is equal or less than the input value. The default is 30. The user can enter a different Fillet Radius and then click Identify Fillets to highlight the identified fillet, as shown in Figure 5.2.17. If mesh does not have this fillet, this function needs not to be used.

● NORMAL ANGLE
This function is used to control the size of mesh segment which determines the size of the generated surface. The default normal angle is 3 degrees. This normal angle is used to calculate the feature lines in the mesh. The user can enter a different angle value and then click Segment Mesh to segment mesh into regions, as shown in Figure 5.2.18. The program will generate a surface for each region.
